Understanding and Confronting Uncertainty: Revisions to UK Government Expenditure Plans

We develop a simple model that motivates fiscal stabilisation policy, in the presence of economic and control uncertainty. An examination of a real-time database of economic variables and forecasts shows that our knowledge of the current and future state of the economy is subject to significant revisions over time. Multi-year government spending plans are also significantly revised over successive fiscal events. We show the risk for any given government expenditure plan by constructing measures of historical expenditure revisions.
